中文摘要:
      设计了一款E 波段高增益天线,该天线由基片集成波导缝隙天线和透射阵组成。为实现足够的相位补 偿范围,设计了多种贴片结构单元。该透射阵共有289 个单元,口径尺寸为33. 065 mm × 33. 065 mm,该天线的焦径比 为0. 45。实测结果表明,加载透射阵后,SIW 缝隙天线的增益提高了14. 63 dB,在74. 23 GHz 增益达到23. 28 dBi,口径 效率为24. 23%,3 dB 增益带宽为10. 83%。
英文摘要:
      A high gain antenna operating at E-band is proposed in this paper. The antenna is formed by a substrate integrated waveguide (SIW) slot antenna and a transmitarray (TA). To achieve large phase compensation, several types of element structure are designed for different phase shifting. The TA is composed of 289 units with a size of 33. 065 mm × 33. 065 mm. The focus-to-diameter ratio (F/ D) of the transmitarray antenna is 0. 45. The measurement results show that the TA effectively increases the gain by 14. 63 dB, and the proposed antenna has a 23. 28 dBi maximum gain at 74. 23 GHz. In addition, the proposed design achieves a 10. 83% 3 dB gain bandwidth and 24. 23% peak aperture efficiency.
